Abstract
This paper describes an immersive system, called 3DIVE, for interactive volume data visualization and exploration inside the CAVE virtual environment. Combining interactive volume rendering and virtual reality provides a natural immersive environment for volumetric data visualization. More advanced data exploration operations, such as object level data manipulation, simulation and analysis, are supported in 3DIVE by several new techniques: volume primitives and texture regions are used for the rendering, manipulation, and collision detection of volumetric objects; the region based rendering pipeline is integrated with 3D image filters to provide an image-based mechanism for interactive transfer function design; a collaborative visualization module allows remote sites to collaborate over common datasets with passive or active view sharing. The system has been recently released as public domain software for CAVE/ImmersaDesk users, and is currently being actively used by a 3D microscopy visualization project.
Highlights
Volume visualization is concerned with the abstraction, rendering and manipulation of volume data sets, such as medical imaging scans and samples of computed/simulated systems
In this paper we describe an environment for volume visualization and exploration called 3DIVE (3 Dimensional Interactive Volume Explorer). 3DIVE employs a region-based approach for volume rendering and data exploration
The shared memory arena between the collaborative module (ColLib) and the CAVERNSoft Information Request Broker (IRB) acts as the repository for interface/state data that eventually needs to be transmitted between participants
Summary
Volume visualization is concerned with the abstraction, rendering and manipulation of volume data sets, such as medical imaging scans and samples of computed/simulated systems. The user could drop “crumbs” inside the dataset and later explore along the constructed spline path It offered slicing planes, color map editor and access to remote supercomputers where image processing could be performed. It is built upon the following characteristics:. In 3DIVE, objects are considered as regions of data sets and represented as collections of volumetric primitives. This allows the user to manipulate and visualize individual portions of the data set, and apply different transfer functions or data filters to individual objects.
